High-loading interventions aiming for muscle-tendon adaptations were so far implemented in on-site facilities. To make this evidence-based stimulus more accessible, we developed an easy-to-use sling-based training set-up home-based Achilles tendon and triceps surae muscle strength assessed its reliability effectiveness healthy men. assess (n=11), intra-class correlation (ICC) root mean square (RMS) differences of isometric maximum voluntary contraction (MVC) the plantar flexors used. Effectiveness was tested a controlled intervention trial (n=12), applying one-legged high-loading 3 months with our mobile set-up, while contralateral/untrained leg served as control, assessing flexor MVC, drop (DJ) countermovement jump (CMJ) height. Reliability excellent between (ICCB=0.935) within session (ICCWs=0.940–0.967). The RMS difference sessions 5.3% 4.7%, respectively. MVCs trained/intervention increased by 10.2±7% (P=0.004) (dynamometry) 30.2±22.5% (mobile set-up) (P=0.012). MVC untrained/control did not change (P>0.05). DJ height (P=0.025; Dz=2.13) 2.37±2.9cm. CMJ (P>0.05) change. We recommend application novel reliable effective improving performance unit.
